' Application filed February 26, 1914.. Serial No. 821,153.

To all whom it may concern:

Be it known that I, FRANK P. DARoY, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Seat- Cushion Structures, of which the following is a specification.

This invention relates to improvements in seat cushion structures.

The objects of this invention are: First, to provide an improved seat cushion in which the entire sewing'thereon' can be done upon a sewing machine. Second, to provide an improved structure inwhich the parts can be quickly and easily assembled and the springs placed and secured therein with a minimum amount of hand labor.

Further objects and objects relating to details and economies of construction will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the device and means described in the accompanying specification. The invention is clearly defined and pointed out in the claims.

A structure constituting a preferred embodiment of my invention is shown in the accompanying drawing forming a part of this specification, in which:

Figure I is a perspective view of a structure embodying my invention. Fig. II is a bottom plan view of said structure. F ig. III is an enlarged sectional viewon the line 3-3 of Figs. II and VI, showing in detail the engagement of the retaining clip with the spring supporting bar and, the auxiliary bottom frame. Fig. IV is an enlarged perspective view showing in detail the engagement of the tongues at the end of one of the spring supporting bars with the auxiliary bottom frame and the border wire of the set of springs. Fig. V. is a plan view of a blank from which the clip shown in Fig. III is made.

my invention. Fig. VII is an enlarged sec- Fig. VI is'a, bottom plan view of a modified form of VIII is a perspective view on an enlarged scale of a modification showing a different arrangement of tongues engaging the auxil ary bottom frame and the border wire.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the drawing, 1 is the top portion of the seat which is padded in any suitable manner. 2 s astrip secured to said cushion portion at its upper edge and forming the side wall portions of said seat. 3 is the auxiliary bottom frame which is made of two s ctions detachably connected together, one Elf said sections being disposed in the pocket formed at thelower edge of the side wall portion 2. This pocket is formed by folding the lower edge of said strip up over the wire forming the auxiliary frame and stitching it. All this is clearly shown and described in my co-pending application, Serial No. 821,152 filed the 26th day of February, 1914. The: front portion of the top 1 is also brought downwardly, as clearly shown in Fig. 1, and the cross bar section of the auxiliary bottom frame 3. is similarly disposed in a pocket formed in the lower edge of said portion.

It will be seen that the top portion and the side wall portion together form a chamber in which-a set of springs 5 is disposed. This set of springs is provided with a border wire 6-, which, in the preferred .form of my invention, extends entirely around the lower edge ofsaid set the springs are carried by-spring supporting bars 7- 7.- The ends of the spring supporting bars 7 are split to. form three tongues. The outer tongues 10, 10 are pointed, pass through the fabric ofthe sidewall portion 2 and are bent downwardly and wrapped around the auxiliary bottom frame of springs and 3. These tongues 10, 10 pass between the border wire 6 and the auxiliary bottom frame 3. The central tongue 11 passes over the border wire 6 and'is wrapped around the same. In this manner it will be seen that the spring supporting bars 7 are 198 curely fastened to the auxiliary hofmatn.

frame 3 and tothe border wire 6 of the set of springs.

To connect the outer spring supporting bars 7 with that part of the border wire and of the auxiliary bottom frame which lies parallel to said supporting bars, I provide a plurality of clips 12 on either side of the set of springs. These clips 12 are made from a blank which is provided at one end with a pointed tongue 13. The body of the blank, just to the rear of the base of the tongue, is provided with a pair of parallel slits so as to form the portion 14. It will thus be seen that when the portion 14: between theparallel slits is struck up it will form an eye or passage. These clips are disposed on the border wirev 6 with said wire 6 passing through the eye or passage formed by the'struck up portion 14:. The body portion 12 of said clip extends transversely of the spring supporting bar 7 beneath the same, and is wrapped around said bar so as to conform to the curvature thereof. The tongue 13 of said clip is passed through the fabric forming the side wall portion 2 and is bent downwardly and back,

. being wrapped around the auxiliary hottom frame 3. In this manner those portions of the auxiliary bottom frame and the border wire 6 lying parallel to the spring supporting bars are securely connected to them.

In Fig. VI I have shown a modified form of .my invention in which the auxiliary bottom frame of the spring structure is formed of two sections, one of which is awire frame 3 such as shown in Fig. 11,- while the other section is formed by a wooden cross bar 4 to which the bottom edge of the front portion of the seat is tacked. In this modification, the.set of springs 5 has a border wire 6 which extends around three edges thereof and the ends of which are bent laterally at v the front of said set so as to extend parallel 'fiattenedso as to bar 4. In this modifront. end of the spring supwith the wooden cross fication, the porting therein, and the front ends of said bars are lie flat on the wooden cross bar 4. The spring supporting bars are so disposed that the channel 8 receives the ends of the border wire 6 lying parallel to said cross fbar 4.- and the front ends of said supporting bars are secured to the cross bar by means of nails 9. The. other ends of the supporting bars are secured to bottom frame and the border wire in the heretofore described. The clips 12 which are also provided are identical with those which I have already des'crihedin reference to Fig. II.

In Fig. VIII I have shown a modification in which I make use of a diiferent arrangement' of tongues on the ends of the spring supporting bars 7. In this modification, the

bars 7 have a channel 8 struck up the auxiliary portion .border wire 6 through the fabric of the side wall portion 2 and is bent downwardly and wrapped around the border wire 6 and the auxiliary bottom frame 3.. In this manner the end of the spring supporting bar 7 is securely connected to the border wire and auxiliary bottom frame. 1

From the description of the parts given above, the construction of this device should be very readily understood. The seat is formed with the side wall portion in two sections and with an auxiliary bottom frame comprising two sections detachably connectcd together. In this respect it embodies part of the invention described and claimed in my co-pending application, Serial No. 821,152.filed Feb. 26, 1914. To construct this seat(,1 auxiliary bottom frame sections are passing through the eye or passage formed by the struck up portion 14, with the body portion of said-- clip extending transversely of the spring supporting bars 7 adjacent said border wire. The tongues 13 are then forced through the fabric of the side wall portion 2 and brought down and wrapped around said auxiliary frame. The body portion of the clip 12 passes underneath the bar? and is wrapped around said bar to conform to the curvature thereof as clearly shown in Fig. III. The tongues on the ends of the supporting bar are wrapped around the border wire 6 and the auxiliary bottom frame 3 so as to engage the same as clearly shown in Fig. IV. In this manner the set of springs is securely held in. position and the parts of the seat cushion structure are securely held together. All this can be done with a minimum amount of manual labor. This makes the cost of producing the springs very slight as compared with other structures known in the art.

The structure shown in Fig. V1 is produced in the, same way except that the wooden cross bar 4 with the lower front of the seat attached thereto is brought beneath the front end of said spring supportingbars and said bars are nailed to said cross bar by means of the nails 9 with the front ends of the border wire 6 engaging in the channels 8.

I am aware that the particular embodiment of my invention which I have here set forth is susceptible of considerable variarea-ear ati'on without departing from the spirit of my invention and, therefore, I do not Wish to be restricted to the same. However, I have found that this form is to be preferred and, therefore, I desire to claim the same specifically as well as broadly as indicated by my appended claims.
